[Rd] serialize changes for 2.4.0

[Roger D. Peng]

I noticed today that in R 2.3.1, I get

 > serialize(list(1,2,3), NULL, ascii = TRUE)
[1] "A\n2\n131841\n131840\n19\n3\n14\n1\n1\n14\n1\n2\n14\n1\n3\n"

but in R 2.4.0 alpha I get

 > serialize(list(1,2,3), NULL, ascii = TRUE)
  [1] 41 0a 32 0a 31 33 32 30 39 36 0a 31 33 31 38 34 30 0a 31 39 0a 33 0a 31 34
[26] 0a 31 0a 31 0a 31 34 0a 31 0a 32 0a 31 34 0a 31 0a 33 0a

It seems I need to use 'rawToChar()' to get the character vector that I used to 
get in R 2.3.1.

Is this intentional?  I couldn't find any mention of this change in the NEWS 
file; from the docs, it seems to me that either return value could be correct.
